responsible for all repair and replacement costs resulting
from damage in shipment.
SAFETY FIRST
2.0 SAFETY ISSUES
Read all instructions, warnings and cautions
carefully. Follow all safety precautions to
avoid personal injury or property damage
during system operation. Enerpac cannot be responsible
for damage or injury resulting from unsafe product use,
lack of maintenance or incorrect product and/or system
operation. Contact Enerpac when in doubt as to the safety
precautions and operations. If you have never been
trained on high-pressure hydraulic safety, consult your
distribution or service center for a free Enerpac Hydraulic
safety course.
Failure to comply with the following cautions and warnings
could cause equipment damage and personal injury.
A CAUTION is used to indicate correct operating or
maintenance procedures and practices to prevent damage
to, or destruction of equipment or other property.
A WARNING indicates a potential danger that requires
correct procedures or practices to avoid personal injury.
A DANGER is only used when your action or lack of action
may cause serious injury or even death.
WARNING: Wear proper personal protective gear
when operating hydraulic equipment.
WARNING: Stay clear of loads supported by
hydraulics. A cylinder, when used as a load lifting
device, should never be used as a load holding
device. After the load has been raised or lowered, it must
always be blocked mechanically.

Control System
DANGER: To avoid personal injury keep hands
and feet away from cylinder and workpiece
during operation.
WARNING: Do not exceed equipment ratings. Never
attempt to lift a load weighing more than
the capacity of the cylinder. Overloading causes
equipment failure and possible personal injury. The cylinders
are designed for a max. pressure of 350 bar [5,000 psi]. Do
not connect a jack or cylinder to a pump with a higher
pressure rating.
Never set the relief valve to a higher pressure than
the maximum rated pressure of the pump. Higher
settings may result in equipment damage and/or
personal injury.
WARNING: The system operating pressure must not
exceed the pressure rating of the lowest rated
component in the system. Install pressure gauges in
the system to monitor operating pressure. It is your window
to what is happening in the system.
CAUTION: Avoid damaging hydraulic hose. Avoid
sharp bends and kinks when routing hydraulic hoses.
Using a bent or kinked hose will cause severe back-
pressure. Sharp bends and kinks will internally damage the
hose leading to premature hose failure.
Do not drop heavy objects on hose. A sharp impact
may cause internal damage to hose wire strands.
Applying pressure to a damaged hose may cause it
to rupture.
IMPORTANT: Do not lift hydraulic equipment by the
hoses or swivel couplers. Use the carrying handle or
other means of safe transport.
